The Amercians with Disabilities Act (ADA) presents some tricky situations. Take this quiz to test your knowledge of the law.

NOTE: Although Congress passed the ADA Amendments Act (ADAAA) in September 2008, that law’s provisions do not take effect until January 1, 2009. Readers who take this quiz in the meantime should base their answers on pre-ADAAA law. We will point out how those answers will change under the ADAAA in the explanation section of the quiz.
